I had the APHA vet visit this morning. To partly answer your question FW I think chances are high we will all be in lockdown again this winter, if not before. I am supposed to be in lockdown now given we are in a blue protection zone but as I (probably rather stridently) pointed out, it is not practical nor humane to lock up a flock of waterfowl just in case a sparrow sh*ts on them!
Having swabbed each goose and duck now have to wait 3 days. If I don't hear by then all will be well, and if not they will be in touch. Chickens and turkeys were just observed at as symptoms are more obvious in those if they have it, and all mine appeared to be well. All waterfowl are swabbed as can be asymptomatic carriers.
